Dental veneers are thin shells, usually made of porcelain or composite material, that are bonded to the front surface of teeth to improve their appearance. In most cases, a very small amount of enamel must be removed to ensure the veneer fits properly and looks natural.
Because enamel acts as a protective barrier, removing even a thin layer can temporarily expose the underlying dentin, which contains tiny nerve pathways. This is the primary reason some patients notice increased sensitivity after the procedure. It is not the veneer itself causing discomfort, but the preparation process needed to place it.
